what does the green colour mean in sleep on Apple Watch? This has happened twice in the last week. Not the light blue napping colour. This is just green
The green colour points to REM sleep, according to the sleep data in the Health App.
But you can tell Apple directly about your wishes for a short color guide in the Sleep app by using the Feedback link:
Do you have a Sleep Schedule enabled?
The watch did not detect your sleep correctly during the time of your Sleep Schedule.
Did you have a look at the Sleep App on your watch?

Did the watch record Sleep correctly before watchOS 26?
Since the watchOS 26 upgrade, the Sleep app on the watch does not work as before. My Sleep app on my Ultra 2 shows long phases of being awake, just because I checked the time while turning from one side to the other, for example. Or it adds a nap after getting up and sitting at the table after breakfast, reading the newspaper on my iPad.
You should also report this directly to Apple Techs by using the Feedback link. The more users do that, the more likely we will see an improvement, hopefully.

In case your watch only did this once, try to force restart your iPhone and Apple Watch. This can clear some glitches on your devices.

To force restart your watch, press and hold the Digital Crown and the Side button together for about 10sec, until the Apple logo comes back again.
Thank you for your reply. Yes I have a sleep schedule on my watch. The app says no recent sleep data but it does show a trend over the last 14 days. I can’t see a score on my watch. I usually check the information in the health app on my phone, but the green is a new thing. Watch is almost 2 years old…
Thank you - your replies have been super-helpful 😊 I will try the resets as suggested and report to Apple as it has happened twice in the last 1-2 weeks. Thank you for providing links too 👍🏻
You're welcome 🙂
I've been dealing with the green color too! Maybe we need a detailed guide, like an instruction manual that doubles as coloring pages, to explain all these Apple Watch metrics!
